Hey, there is nothing wrong with the fuzzy feeling from using Motorcraft oil and filters at the recommended interval by Ford.
You sleep good, you don't care, and you blame all evil on Dearborn.
Then there are the nuts (like me) who are reviewing engineering tests, specs, field reports, trying to find the perfect oil.
But that is not for everyone.
BTW, I found Valvoline Extreme Synth at $22 a gallon... me happy.

I live in a rural area near a farm store -- they had all sorts of HD diesel stuff cheap.. from $20 filters for the 6.0, to oil, etc.
Do you have a chain of farm stores near you?

ACEA E9 oils are expected to be SAE 15W-40 based on API Group II base oils. ACEA E9 is a new category within the heavy duty oil sequences.

Yes, the devil is in the details --- what sort of a test setup, how long is the test run...etc.
Ideally, I want to see the two standards, with the precise setup and procedure described, posted.

Even if you change your oil more often than you change your underwear, a by-pass system keeps it cleaner all the time and nothing could be wrong with that?
Without a 1 micron filter there is 4500 times more particles than with!
And of course, as long as the truck is under warranty you should not interfer with factory recommendations.

There have been posts in the past that showed oil analyses with a bypass filter and without. There were no appreciable differences between the two after the normal service interval. A bypass filter is of little use for an engine that is running well and fluid that is being changed at the proper service life. It can be useful in circumstances of severe service or when a component might fail. As far as going past the recommended service interval, that has been addressed very well - No bypass filter can restore a 40 weight viscosity that has dropped to almost a 20 weight in 7500 miles. It also can not restore detergent properties that have deteriorated from service life (reaction with soot and acids formed from combustion). The data is out there on a 6.0L application - which is the only thing that is of consequence on a 6.0L forum.

revolverivar...we're not just talking contaminants in the oil. We're also talking oil breakdown. Please remember that the 6.0 diesel uses high pressure oil to make our injectors function. This creates a whole 'nother issue for us.

The dirt comes from combustion and thats the largest source of wear on your engine. Acids and water binds particles and make more wear. Remove it in an efficiant filter and you reduce wear, its no rocketscience.
Thats why I would have a bypass filter even if I changed oil every day. In any other case I agree with you all. We all want the same thing, the best care for our trucks.
Why does the Ford 6.0 destroy the viscosuty worse than another engine?

Do some oil analysis on your oil at the end of a service run. Post it here. Also, compare it to the posted 6.0L UOA on BITOG for the same oil. I doubt you will see any difference. You are right - it truly isn't rocket science (this has all been done many tmes over in the past 6 years). Almost every type of oil has been analyzed multiple times. A bypass filter will no doubt reduce wear. The question is "will it reduce it enough to make a difference in the length of time you plan on owning your truck (and before something else fails and causes you to sell it)".
One of FTE members (IIRC - Beachbumcook) did a comparison of oil analysis with and without a bypass filter. The results were posted here. I will see if I saved the links.
Oil viscosity issues in the 6.0L engine come primarily from the abuse the oil takes in the HEUI system (tolerance, pressures and heat, shear forces, etc in the HPOP, IPR, injectors).
Here is an overview of an article that mentions shear in our engines:
